Male crickets give the female an edible packet of proteins to consume during mating. This sort of "nuptual gift" is fairly common in insects, and may allow physiological and behavioral changes that increase the chance of a successful mating! The longer it takes the female to eat the packet, the better the sperm transfer. Other insects give dead insects or even their own body as part of this pre-nup arrangement, so seems like crickets are getting off pretty easily (no pun intended!).
It might seem intuitive to animal lovers that being with animals would be a good thing, and that is what much of the research on animal assisted therapy suggests. The problem is that these studies are fraught with problems (such as lack of controls and small sample sizes) that make it hard to trust the results. Perhaps the field needs some outreach on experimental design?? Hal Herzog tells us what's up here.
